STREET-CLEANING DEVICE.

. SPECIFICATION forming part of Letters Patent N0. 642,937, dated February 6, 1900.

Application filed April 5, 1899. Serial No. 71 1,791. (No model.)

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters and numerals of reference marked thereon, which form a part of this specification.

This invention relates to certain improvements in that class of street-cleaners, more particularly for asphalt and brick pavements, represented by the one shown in my prior application for a patent filed February 16, 1898, Serial N 0. 670,577, the objects of the present improvements being to secure a more perfect cleaning; to enable clods of dirt or other matter upon the pavement to be broken up or subdivided, so as to enable the brush and scraper to more perfectly act thereon; to provide means whereby stones, wooden sticks, branches of trees, &c., which would tend to clog the mechanism of the device, are prevented from entering the machine; to enable the device to gather the said sticks, stones, &c., at the front of the machine, where the operator may from time to time conveniently gather the same and insert them into the bag or receptacle for the dirt separably attached to the machine; to enable the dirt after having been brushed upon the scraper-and connections to be more perfectly and easily elevated therefrom and to prevent the said dirt from falling back upon said scraper and thence to the pavement; to secure a more perfeet and even contact of the scraper with the road-bed, whereby the dust is scraped up with a greater perfection, and to secure other advantages and results, someof which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved street-cleaning apparatus or device and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings,

in which like letters and numerals of reference indicate corresponding parts in each of the several views, Figure 1 is a side elevation of the improved street-cleanin g device. Fig. 2 is a detail perspective view showing means of attaching and detaching the bag or receptacle for the dust from the machine, and Fig. 3 is a plan of the said apparatus or device. Fig. 4 is a side elevation in detail of the lower part of one of'the side frames and cooperating parts. Fig. 5 is a section of the same on line 00. Fig. 6 illustrates the upper part of a bag or receptacle for the dust or sweepings. Fig. 7 is a perspective detail of a certain transverse tie-piece, and Fig. 8 is a detail view of a rake adapted to be formed at the front of the device.

In said drawings, a indicates the frame of the device, comprising suitable side frames a and transverse tie pieces or strips a joining the said side frames and holding the same in vertical position. The said side frames each comprise upper and lower longitudinal metal strips a a the lower strips serving as cheekpieces for the bottom board of the slideway and projecting above the upper face of said bottom board to form dust-guards for said slideway. The said side frames at their up per or rear parts have rearward extensions b, which serve as handles or receive a round connecting-bar b, which serves as a handle by means of which the operator may conveniently push the device forward. At its lower part the said side frames have downward extensions a a, which join at points about midway between the ends of the slideway and provide bearings a for a main driving-shaft c, which extends from side frame to side frame of the device, and at or about the center is provided with a broad-faced wheel d, adapted to engage the ground, the said wheel being broad-faced, as described, to afford ample frictional contact with the ground or pavement to prevent slipping in supplying power by means of which the operating mechanisms are driven. The said shaft 0 at one side carries a sprocket-wheel at, similar to the one shown in the prior case above referred to, adapted to receive a power-transmittin g chain or belt 6, by means of which motion is conveyed or transmitted to an upper sprocket wheel or wheels f, arranged at the top of the frame on a shaft f ata point a little forward from the handles 1), sufficient space being provided between the slideway, shaft, and handle to permit a bag A to be suspended from the top of the frame and to permit a passage of the dirt into said bag. Upon the said shaft f is arranged a second sprocketwheel or set of sprocket-wheels h, which 00- operate with sprocket-Wheels 2 on short shafts t" at the lower and forward part of the frame a, and on said sprocket-wheels h z are arranged endless chain belts j, which extend at inclines of an angle of about forty-five degrees, more or less, and carrya series of conveying-strips 7t 7t 7;, and upon the frames adjacent to the lower parts of said belt or belts is secured an inclined way B, which may be of wooden board, sheet metal, or sheets of compressed paper, over which the said conveyingstrips 76 7o slide, propelled by the chainsj and connections with the main driving-shaft.

Closely adjacent to the lower sprocketwheels 1' the inclined way is provided with a pocket m, formed of sheet metal, and at the rearward side continuing the inclination of the inclined way and at the front curving upward from the plane of said inclined way, the curve in the pocket being preferably concentric with the shaft upon which the lower sprocket-wheels c' revolve.

The ends of the pocket are closed by the castings n, forming the lower end sections of the side frames, the rearward ends of the castings being recessed in the lines of the strips a a to receive the ends of said strips, which latter are firmly riveted in place. The lower ends of the casting are semicircular, and at their foremost edges are provided with lugs 01, which are perforated and receive 'pivotal extensions n .of a scraper-bar n upon which last the scraper-plate 0 is riveted. The sheet metal forming the pocket extends to or nearly to the said scraper-bar, where it terminates to permit a passage of dust or dirt from the scraper into said pocket.

The castings n at or near their centers are provided with bosses which are cored or bored out to receive the short shafts 2', said short shafts being held in said castings in the manner indicated in Fig. 5 or in any othernnanner.

The sprocket-wheels 2' are preferably loose on the shafts i, the latter being preferably rigid and fixed in the casting n, and said shafts 11' extend through and out beyond the outer sides of said castings to receive slotted supports 13 for a brush-carrier frame q. Said brush-carrier frame comprises side strips q g, which extend from the main driving-shaft 0, upon the ends of which said strips are suspended,forward to said supports p,where they are adj ustably held by clam p-screws r or other suitable means. From the supports the said strips extend farther forward to points approximating the forward edge of the scraperplate 0, where said strips q q are provided with boxes or bearings for a rotary brush 8. On the axle of said rotary brush is arranged a sprocket or chain wheel t, which is connected by an endless chain a to a large sprocketwheel '0 on the main power-shaft, so that the said brush is rotated by the power derived from the wheel cl, on which the device is trundled by the operator. The strips q q are connected to complete the frame g by a cross connection q ,whieh is preferably raised between its ends to form a support for a cap 3, said cap being secured upon said support by riveting or otherwise and inclosing said brush and other working parts to protect said parts from improper interference and keep the dirt thrown by the brush within proper bounds.

The lower part of the cap 3 at the front is open and preferably provided with rake-like teeth 4, adapted to enter into compact masses of dirt to loosen the same, so that the scraper and brush may act thereon more effectually and to catch and collect large stones, sticks,

pieces of tin, or the like, such as would tend to clog the mechanism described, and thus render it convenient for the operator to gather said stones, sticks, &c., for insertion into the bag by hand.

At the upper ends of the side strips a a the same are secured to and joined by the castings 5, which provide bearings for the shaft f, and a hood 6, which is preferably hinged at 7 to the upper of said castings 5. Said hood protects the operator from the dust as it falls into the bags suspended upon bars 8 8, extending in parallel lines across from one handle extension I) to the other. The bag is provided at its upper edges with a series of hooks (shownin detail Figs. 2 and 6) adapted to catch upon said bars 8 8, and when the bag is full to clasp or hook upon one another, the hooks upon one side of the bag catching upon those on the oppositeside thereof, so that the closing of the bag is greatly facilitated.

Above the slideway of the device I prefer to arrange a bag-support 9, consisting of a coarse wire network stretched upon a suitable framework. Said framework is bent upward at its rear end and provides bearings for a crossbar 10, over which the empty bags may be folded and thus held upon the support. Said bags are thus stored upon the device ready for use. Said bag-supporting frame and network may be fastened to the side frames in any suitable manner. The said side frames,

preferably the lower bars or strips a thereof, are provided with a series of buttons 15, upon which the side edges of a canvas cover (not shown) may be fastened, the said canvas cover extending from the hood 6 to the cap 3 and down at the outersides of the side frames,

and thus effectually preventing the escape of dust.

Having thus described the invention, what I claim as new is-- 1. The improved street-sweeping apparatus, comprising an inclined frame having dirtelevating means, a Wheel and handle and a scraper, a brush and means for rotating the same, and a cap having rake-teeth at the front adapted to protect the brush from heavy stones, sticks and the like, substantially as set forth.

2. The improved street-cleaning apparatus, comprising an inclined wheeled frame having elevating means, a scraper, sweepingbrush, a handle, and means for transmitting power, and an inclined empty-bag-supporting frame arranged on and supported by said frame and holding said bags up and away from the elevating means, the said inclined empty-bag-supporting frame having at its upper end an upturned part to which a horizontal bar is secured over which last the empty bags may be folded and carried along as the device is pushed forward ready-to be removed one after another as the suspended bags are filled substantially as set forth.

3. In a street-sweeping apparatus, the combination with aframe, comprising connected side frames having parts a a a a, n joined together, the parts a aflconnecting with one another at the main driving-shaft, and providing bearings therefor, of said chain and a sprocket-wheel for the dirt-elevating means and a wheel upon which the device is trundled, an inclined way B, over which the dirt may be raised, a chain belt j, having elevating-strips k, a scraper and a brush arranged in front of the scraper and adapted to sweep the dust thereon, and driving-chains, all arranged and adapted to operate, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 25th day of February, 1899.

GEORGE M. WARD.
